49ers officially announce DeForest Buckner trade, release CB

The San Francisco 49ers have officially announced their trade for defensive lineman DeForest Buckner from the Indianapolis Colts in exchange for a 2027 fourth-round draft pick. The deal was first reported on Tuesday.

To make room for Buckner on the 53-man roster, the 49ers released cornerback Jack Jones, who struggled in Sunday's loss to the Atlanta Falcons.

The 49ers Communications staff provided the following rundown.

The 49ers originally drafted Buckner (6-7, 295) with the seventh overall pick in the 2016 NFL Draft. Over his 11 seasons with San Francisco (2016-19) and Indianapolis (2020-26), he has played in 158 games (153 starts) and recorded 682 tackles, 75.5 sacks, 31 passes defensed, 11 fumble recoveries, and nine forced fumbles. He has also started in four postseason contests and totaled 14 tackles, 2.5 sacks, one forced fumble and one fumble recovery.

In 2026, Buckner started seven games with the Colts and recorded 31 tackles, 4.0 sacks, three passes defensed, and one fumble recovery.

Buckner has been named an Associated Press All-Pro twice (First-Team – 2020; Second-Team – 2019) and has received Pro Bowl honors three times (2019, 2022 & 2024). He was also selected to the Pro Football Writers of America All-Rookie Team in 2016 and earned a PFWA All-NFL Team selection after the 2020 season. During his first stint with the 49ers, he received the 49ers Thomas Herrion Memorial Award (2016), Hazeltine Iron Man Award (2017-18), Len Eshmont Award (2018) and Bill Walsh Award (2019).

A 32-year-old native of Honolulu, HI, Buckner attended the University of Oregon for four seasons (2012-15), where he appeared in 54 games and registered 232 tackles, 18.0 sacks, 36 tackles for loss, and nine passes defensed. As a senior in 2015, he earned Associated Press Second-Team All-America honors and Pac-12 Defensive Player of the Year.

Jones (5-11, 175) appeared in seven games this season, recording 11 tackles and three passes defensed.
